Hi guys i'm pretty new to rooting xperia v. decided to root a spare phone lying around in the house.
I entered cmw and wipe date and install rom and kernel, i rebooted and the screen stays blank.
i pressed the power button and it vibrated and still went blank? Would need some advice. tyvm
Your bootloader might be locked.
Maybe,you can only flash stock ftf now

Hey guys!
I have madea mistake and need your help... Today I finally decided to unlock the bootloader. That went ok. Then I wanted to install a custom rom, namely PAC. I was on stock 434 firmware. I then proceeded to flash boot.img from PAC to get the recovery (big mistake, I know). And now the phone is stuck turned on with a black screen and I cant turn it off at all
If i wait for the battery to die and then try to enter fastboot mode and install another boot.img (doomlord for 434 firmware) will that be possible or what should i do :S Hope its not permanently bricked...
Thank you for your help!
No big deal, just don't get nervous when things like this happen.
Ok, so first, to turn off the device, you have to hard power it off by pressing Power Button plus Volume Up together until the phone vibrates three times. Now that the phone is turned off, you might as well try to enter recovery by pressing volume up after the purple led flashes (if the kernel was installed correctly the first time).
If you get a black screen still, download EMMA Flashtool, follow the instructions to bring your phone back to life.
Now you are now on stock rom and kernel and you might as well give it another shot.
Keep in mind that flashing first the PAC kernel to get recovery is not a mistake. Kernel is not rom dependant, as long as there is a kernel with recovery booting, it don't matter if the rom is not compatible with the kernel (like in this time, you have pac kernel, and a stock rom over it, right?)

Thank you for your help! Worked like a charm, got my PAC and smile back :laugh:
So I was about to move from CrystalPA back to the latest FXP CM11 build, i backed things up, went into clockworkmod, did all the needed wipes and was about to flash when I realized I downloaded the honami version instead. So I was downloading the right version but the download took about an hour, i left my phone in CWM while the download was going and by the time it was finished, my phone died. Now I left it on charge overnight so it should have been fully charged but I dont think it did much charging. I got to being able to switch it on and seeing the sony logo but because I'd already done all the wipes (system, data, cache, dalvik) it couldnt boot. I then used the button on the back to switch off and tried to enter recovery by holding vol + when i switched on, then i tried vol -, then i tried the camera button. Nothing happened, just sony logo then a black screen. After a few attempts, the phone is now flashing red when I try to turn it on, and when I plug it into charge, its just a constant red light (brighter than normal charge light).
Does anyone have any suggestions on how to revive my phone?
Thanks
Did you try to push vol -/+ buttons a few times instead of holding them?

I didnt, and i cant now because its just doing red lights only, Ive managed to get it into flashmode so im going to just restore it back to full factory with flashtool and just start again. Hope it works, the flashtool log is saying "device: unknown"
Edit: So the flashing worked, got back to 254 firmware with the old FTF file I still had, I then had to make my own 205 firmware FTF with XperiaFirm and Flashtool, I then flashed the new 205 firmware because Sony PC Companion wouldn't update my phone as its unlocked (i think?). Now all I have to do is install CWM, root and then get CM reinstalled.
I warn everyone - do not leave your phone in recovery when its running low on battery! youll have to start from square 1 if it dies!
Don't need to reflash ftf, just extract boot.img from cm zip and flash on flashtool, then just enter recovery and install cm
Use Lucas's method in the future.
Flashing a recovery-ready kernel is easier you know Anyhow, glad to know your SP worked again.
Hey there,
I followed the guide on XDA to root my Xperia SP with the Towelroot app. The guide is here:
http://forum.xda-developers.com/showthread.php?t=2783885
I then rebooted my phone into recovery, and flashed the latest build.
I rebooted the phone and downloaded the latest Cynagonenmod 12.1 nightly build for the Xperia SP. Once downloaded I wiped my phone and installed the ROM using the TWRP recovery that I'd installed before. At that point I powered off the phone whilst I downloaded the Gapps package on my PC.
When I returned to my phone to try and turn it on nothing happens. It won't turn on or even load the splash screen when I press the power button.
When I hold the power button , the phone vibrates and nothing more! The reset button on the back of the phone does nothing either unless the phone is plugged into a PC. Even then, the phone vibrates 3 times but still won't turn on properly.
I have gone through the Flashroot tutorials over the last 3 hours trying to solve this problem but I've had no success.
I have found that if I hold the volume key down and connect the phone to the PC then the green light appears on the bottom bar of the phone for a period of about 40 seconds before turning off again. It then turns back on and repeats the process.
I am unsure what to do next. Sorry for the long post.
Any help is much appreciated!!
Flashtool progresss
Sorry for the bump but if this helps anyone that could potentially help me. Here is what happens when I try to use Flashtools to flash a stock ROM onto the Xperia SP.
EDIT: Don't worry I solved the problem. I instead used the PC Companion tool to recover my phone and it worked a charm!
I realised the mistake I made. I tried to install Cyanogen Mod 12.1 without an unlocked bootloader which is what likely caused the brick.
Hello all,
I've "inherited" my brother's Xperia SP. I've rooted it before, so now that I "own" it I've decided to flash a custom rom on it. When I flashed the rom and gapps, tried to restart, now it won't boot. I flashed using TWRP. Not bootloader is not unlocked, and neither can it be unlocked.
It doesn't even want to charge, I plug it in, but it is not reacting at all.
When I press the off button at the back, and the press the power button, I get a soft quick vibrate and then nothing happens. I go press and hold on the off button again, and try power + vol down. I get the middle notification light to flash green quick and then disappears. Nothing happens.
Help? I followed and read up instructions to install the ROM. I was on the 4.3 stock before flashing.
How I flashed: went to TWRP, factory reset, wipe system, install rom, install gapps, restart. Did I screw up somewhere? I feel like I might have, but I didn't think it would get bricked when I have a locked bootloader. Any insight to what might have happened, at least? Thanks.

I don't remember the thread, but the file name is this one: Slim-huashan-5.1.1.beta.0.12-UNOFFICIAL-20151119-1622.zip
Now that I go through the stuff, I see what you mean that witha locked bootloader I can only flash a limited selection of roms... What bugs me is that the phone isn't even starting up. Not charging. PC can't see it either.
When I turn on, just a soft vibrate and then nothing. I press the off button at the back, and then press and hold vol down + power, the middle green led flashes once, and then nothing. If I connect to charger and hold the off button, it vibrates three times and then nothing. I try again, it vibrates two times. I don't get it. :S
I feel like I screwed up big time. (won't be the first time) but I'm curious is this is really dead or is there something I can still do about it.
It's a softbrick. You need to find an official firmware for your SP and flash it flashtool. You can look on the forum for guides for this.

It seems you have soft bricked your phone by flashing that ROM.
For installing official firmware, this video tutorial can help you.

Thanks! I got it back! The video helped! :good:
I guess I'll stay on stock for now, and do more reading.
done something stupid, I made a full wipe then restarted the system..now my computer is not seeing my phone, lost recovery, bootloader (I think) and I am stucked on the bootscreen
any ideas? thanks
Turn off by pressing power + volume.up until the phone vibrates three times.
Then flash any stock rom with Flashtool. Take a look at the general section...
It worked! Thanks bro
